I second Christian's recommendation for MobileIron as a good third party cross platform mobile management solution. The issue of data protection is more complex and requires a holistic approach beginning with an understanding of the specific mobile platform security capabilities, the applications being used, and the sensitivity and impact risk of the data. Generally the most common mobile platforms (iOS, Android, Windows Phone) support on device data encryption, preventing unauthorized data access from outside the device, and forced VPN tunnel solutions, to ensure that all communication from the device to corporate services are secured. There are a broader range of attacks possible and that is where the security models of the platforms differ.

Mobile devices are like rabbits: tiny, cute and rapidly multiplying. So when you want to develop application each document remains secure while allowing users to remain productive and collaborate safely.

Basically everything is depends on your application requirements what are different aspects you want while developing mobile application. so you can have content management, Email and Notifications management, maintenance queries in short fast support, etc. on go.
